Bridge beam sizing is based on Harrington products’ weights and speeds
1. Includes 15% allowance for Electric Hoist load factor.
2. Based on Harrington’s electric chain hoist product.
3. For spans greater than 10 ft, braces between end truck and bridge beam are recommended.

All motorized bridge cranes require a master panel to control bridge crane functions. Harrington control
panels are completely pre-wired and tested, and ready to mount on bridge beam. Standard panel is
NEMA 1 rated and includes:
Through-the-door fused
disconnect switch is OSHA
compliant lock-out capable
Main line contactor
allows the crane to be turned
on and off from the pendant
Reversing contactor
provides bridge crane
forward and reverse control
Thermal overload relay
(auto-reset) protects crane
drives from overheating
21
Control transformer
(with primary and secondary
fusing) provides low voltage
control circuit for pendant
Fusing for crane drives protects
motors and are NEC compliant
Electric Acceleration
Control (EAC) allows easy field
adjustment of crane acceleration
and helps minimize load swing
NEMA 4 bridge crane control panels available upon request.

B r i d g e C r a n e C o n t r o l P a n e l s
These panels are for use with all Harrington Series 3 motorized end trucks and are NEC compliant for
